在OS X操作系统下设置MySQL root用户密码

我刚刚在Mac OS x上安装了MySQL，下一步是设置root用户密码，所以我接下来这样做:

启动终端应用程序以访问Unix命令行。在Unix提示符下，我执行了以下命令: cd /usr/local/mysql/bin ./mysqladmin -u root password' password'

但是，当我执行命令时

./mysql -u root，这是答案:

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 224

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

我不需要密码就能进入mysql命令行!

为什么会这样?

mysql网站上提供的说明非常清楚，比上面提到的还要清楚

$ sudo /usr/local/mysql/support-files/mysql服务器停止 $ sudo /usr/local/mysql/support-files/mysql服务器启动——skip-grant-tables /usr/local/mysql/bin/mysql mysql> FLUSH PRIVILEGES; mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass'; mysql>退出或按Ctrl + z $ sudo /usr/local/mysql/support-files/mysql服务器停止 $ sudo /usr/local/mysql/support-files/mysql服务器启动 /usr/local/mysql/support-files/mysql -u root -p 输入新密码，即MyNewPass

这就是对我有效的方法:

Make sure no other MySQL process is running. To check this do the following: From the terminal, run this command: lsof -i:3306 If any PID is returned, kill it using kill -9 PID Go to System Preferences → MySQL → check if any MySQL instances are running, stop them. Start MySQL with the command: sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables The password for every user is stored in the mysql.user table under columns User and authentication_string respectively. We can update the table as: UPDATE mysql.user SET authentication_string='your_password' where User='root'

当我安装OS X v10.10 (Yosemite)时，MySQL出现了一个问题。我试了很多方法，但都没用。其实我找到了一个很简单的方法。试试这个。

首先以超级用户(su)权限登录到终端。 sudo苏停止MySQL sudo /usr/local/mysql/support-files / mysql。服务器停止安全模式启动: Sudo mysqld_safe——skip-grant-tables 打开另一台终端，以su权限登录，然后无需密码登录MySQL客户端(MySQL) Mysql -u root 修改密码更新mysql。SET Password ('new_password') WHERE user ='root'; 冲洗的特权冲洗特权; 现在你完成了。

停止MySQL服务器

sudo /usr/local/mysql/support-files / mysql。服务器停止

以安全模式启动MySQL

Sudo /usr/local/mysql/bin/mysqld_safe——skip-grant-tables &

修改root用户密码

/usr/local/mysql/bin/mysql -u root

use mysql;
UPDATE user SET authentication_string=PASSWORD('NEW_PASSWORD') WHERE user='root';
FLUSH PRIVILEGES;
exit

测试

执行/usr/local/mysql/bin/mysql -u root命令

现在输入新密码开始使用MySQL。

关闭MySQL服务器

进入系统首选项-> MySQL 单击停止MySQL服务器按钮

打开两个终端[命令行]窗口在第一个终端窗口中运行以下命令:

在第二个终端窗口中执行以下操作:

4.1. 登录MySQL

mysql -u root

4.2. 在MySQL提示符中执行如下命令:

FLUSH PRIVILEGES;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'NEWPASSWORD';

4.3. 退出MySQL

exit;

回到第一个终端窗口并关闭mysqld_safe

5.1. 按CTRL + Z

5.2. 运行以下命令

mysqladmin -u root -p shutdown

5.3. 输入在4.2中设置的新密码。当提示。
